Mmh, thx, I just copied and pasted it from the instructions from the main page... So it must get corrected there as well...

Thank you, I will try it later!

edit:

For the sake of completeness, I want to mention, that @Ernst79 already gave the hint in the comments section of "Building a MQTT Gateway" Install-Instruction on the mainpage. I just did not see it, but I would love to see @tbowmo to add this line to the code. Thank you!
